How can I import IRK in nRF Sniffer BLE version?

[KaiRen@HiHonor]

Hi,

I noticed that latest nRF Sniffer BLE version support importing IRK, however, I can't make it successful, do you have a step-by-step guide for IRK importing on wireshark?

Hi Kai, 
First you would need to extract the IRK either from the device or from the peer when you bond. 
After that you put the IRK to the Value box and choose Key "IRK". The Device you should choose "Follow IRK".

Please pay attention to the endianness of the Key.

This works for me:

Thank you. One more question, for Android device HCI snoop log, do I need to convert the endianness or it can be used directly?

Unfortunately I don't have much experience with the HCI snoop log on Android. But it's only 2 possibilities (bytes endianess not bit endianess) please try
